Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply rail stability meets the component specifications to maintain frequency accuracy. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided in the manufacturer documentation.

Oscillators Selection Notes

Select this component when a precise 30.0075 MHz reference is required in space-constrained designs. The LVCMOS interface ensures direct compatibility with standard digital logic families. Consider the power-down feature if energy efficiency during idle states is a critical design parameter for the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal components. The series offers various frequency options within a standardized small outline package format. Mercury Electronics has established itself as a pioneer in the Taiwan quartz industry, providing reliable frequency control solutions since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and form factor but different frequencies, such as 18QHTF21-30.300-PD or 18QHTF21-51.200-PD. Cross-brand replacements require matching LVCMOS output, 1.8V supply, and 4-SMD No Lead package constraints.
